Innovative Digital Inline Holography: from Flow Measurements to Cancer Diagnostics

Particles (e.g., dust, cells, droplets) with size ranging from nm to mm are ubiquitous in our daily life. To determine their properties in situ is vital for many applications. Here I will share with you our recent advancement in both the instrumentation and computational algorithms of digital inline holography (DIH) as a low cost and compact tool for 3D imaging of particles suspended in the flow. Enabled by such advancement, we have implemented DIH not only to study fundamental problems in the field of fluid dynamics, but also characterize particle properties and behaviors in agriculture, meteorology, medical sciences, microbiology, material sciences, etc. A number of such examples including measurements of wall-bounded turbulent flows, characterization of risks of airborne disease transmission, and detection of cancer cells in a blood stream will be provided.
